Large-angle universal crushing hammer

Abstract

The invention discloses a large-angle universal crushing hammer. The large-angle universal crushing hammer comprises a crushing tip, a hammer body connected with the crushing tip and protective platesfixed on the two sides of the hammer body, wherein the protective plates on the two sides are symmetrically arranged on the left and on the right of the hammer body, the crushing tip is exposed at the front ends of the protective plates, and pin shaft assemblies distributed triangularly are arranged at the rear ends of the protective plates on the two sides; the pin shaft assemblies are the pin shaft assembly A, the pin shaft assembly B and the pin shaft assembly C; and the pin shaft assembly A is away from the crushing tip compared with the pin shaft assembly B and the pin shaft assembly C.The large-angle universal crushing hammer is simple in structure, the shape of the protective plates is different from the shapes of triangular and vertical protective plates in the prior art, three sets of the pin shaft assemblies distributed triangularly are arranged at the rear ends of the protective plates, an operator can selectively switch connection of an excavator, the pin shaft assembly Aand the pin shaft assembly B or the excavator, the pin shaft assembly A and the pin shaft assembly C, the rotation operation directions of the excavator connected with the pin shaft assembly A and the pin shaft assembly B or the excavator connected with the pin shaft assembly A and the pin shaft assembly C are not exactly the same, the rotation operations of the pin shaft assembly B and the pin shaft assembly C mutually compensate, and the operation range angle of the crushing hammer is greatly enlarged.

Description

technical field [0001] The invention relates to the technical field of breaking hammer mechanical equipment, and more specifically relates to a large-angle universal breaking hammer. Background technique [0002] In construction, when the intention is to break rock, concrete or some other harder material, a breaker is often used, and is often used as an attachment in an excavator or other working machine. The breaking hammers on the market are divided into triangular type and vertical type according to the shape of the guard plate. Whether it is a triangular or vertical guard plate breaker, the pin shafts on the guard plate are two groups. The two sets of pin shafts of the triangular guard plate breaker are located on the same side of the guard plate and are inclined to the side, and the two sets of pin shafts of the vertical guard plate breaker are located on the top of the guard plate. The stroke of the arm and the telescopic oil cylinder is fixed, and the position of the...

AI Technical Summary

Problems solved by technology

The crushing tip of the breaking hammer cannot be rotated upwards. When it is necessary to crush the top of the object to be crushed from the bottom up or the object to be crushed is slightly higher, the existing crushing hammer is limited by the angle of its operating range and cannot work.

The fixing of the breaker guard plate and the hammer body of the crushing tip, during the use of the breaker, generates strong vibrations, and as time goes by, the installation of the breaker guard plate and the hammer body of the crushing tip may be loose and misplaced, which may affect the crushing effect
